I'm glad they finally decided to add this system. I think it's about time they did this as it opens business up to more people. I'm not too fond of paying with a credit card since it's spending money I can't see (until the bill arrives that is).
One thing I am still wondering is whether this is available in Canada as well. When GameStop is mentioned, it's usually implied that it only applies to the US branches, but that's only a rule of thumb.
